CHARLES H. JOHNSON, OF VIRGINIA, MINNESOTA.

SPECIFICATION forming part of Letters Patent No. 557,824, dated April*7, 1896. Application led Tune 4, 1895. Serial No. 551,605. (Nomoclel.)

To @ZZ whom it may concern:

Be it known that I, CHARLES H. JOHNSON, of Virginia, St. Louis county,Minnesota, have invented certain Improvements in Drill-Pullers, of whichthe following is a specification.

My invention relates to improvements in drill-pullers, its object beingto provide a simple device for lifting drills or stakes out of theground.

To this end my invention consists in providing a pair of similarcam-jaws pivotally connected together, their adjacent facesbeingserrated to better grip the drill. These jaws are provided withoutwardly-projecting and downwardly-bent arms, each of said arms beingformed with a bottom groove, into which the crowbar used for lifting thedevice is adapted to fit and be thus held from slipping out ofengagement with the arms.

My invention further consists in the construction and combinationhereinafter particularly described and claimed.

In the accompanying drawings,formin g part of this specication, Figurelis a view of my device shown in use with a drill. Fig. 2 is a plan viewof my device, and Fig. 3 is a side view of the same.

In the drawings the drill-puller A is made up of the pair of similarcam-jaws 2 and 3, provided with the outwardly-projecting anddownwardly-bent arms 4 and 5. The jaws 2 and 3 are connected togetherand held the required distance apart by means of the tie plates orstraps 6 upon either side of the jaws and the bolts 7 passing throughthe plates and through eccentrically-arranged holes in the jaws. Theadjacent faces 8 of the jaws are serrated, so as to securely grip thedrill 9. The downturned end of each of the arms and 5 is formed with theside iianges l0 to prevent the crowbar ll slipping out of engagementwith the arms in the use of the device.

In use the device is placed, as shown in' Fig. l, with the drill orstake projecting upward between the serrated faces 8. Blocks l2 thenbeing placed beyond the ends of the downwardly-bent arms and crowbarsinserted underneath and resting upon the blocks, by pressing downwardupon the outer ends of the bars the cam-jaws will be turned upon theirpivots into engagement with the drill, lifting it upward, as shown indotted lines in Fig. l. The serrated faces of the jaws give a iirm holdupon the drill and prevent slipping. The crowbars then being released,the device will drop down, the operation of lifting being repeated untilthe drill is entirely lifted out of the ground.

I claiml. In a drill-puller, in combination the pair of cam-jaws, theplates connecting said jaws, the pivot-bolts passing .through saidplates and jaws, and the outwardly-projecting arm upon each jaw providedwith a groove or socket to receive a lifting-lever.

2. In a drill-puller, the combination of the pair of similar curvedcam-jaws having serrated faces, the connecting-links, their commonfulcrum-pivots passing through holes eccentrica-Hy arranged in saidcams, the outwardly-projecting depending arms upon said cams, and thedownwardly-proj ectin g flanges upon said arms constituting a groove orsocket to receive a lifting-lever.

In testimony whereof I affix my signature in presence of two witnesses.

CHAS. H. JOHNSON.
